A process used to form a perfect square trinomial. To complete the square of $$x^2+bx$$ and add $$\left(\frac{b}{2}\right)^2$$ .

The sum of all the values in a data set, divided by the number of data values. Also called the average.

The equation of a straight line in the form, $$y=mx+b$$ where m is the slope of the line and b is it's y-intercept.

The line with the slope $$m$$ that contains the point $$\left(x_{1\ },\ y_1\right)$$ can be described by the equation, $$y-y_1=m\left(x-x_1\right)$$ .

A method to solve systems of equations by solving an equation for one variable and subsisting the resulting expression into the other equation(s).

A line that divides a coordinate plane into two half-planes.

The part of a coordinate plane on one side of a line, which may include the line.

The set of all second coordinates (output or y-values) of a function or a relation.

A relation in which every domain value is paired with exactly one range value.

A test used to determine whether a relation is a function. If a vertical line crosses the graph of a relation more than once, the relation is not a function.
